[PATCH] add __ARM_ARCH_6ZK__ to cpukit/score/cpu/arm/rtems/score/arm.h

[Cudmore, Alan P. (GSFC-5820)]

This is the only non-bsp file I needed to change to support the Rasberry Pi. 
The Pi uses the Broadcom 2835, which in turn has the ARM1176jzf-s core. When I use the -mcpu=arm1176jzf-s option to build the BSP, the compiler defines __ARM_ARCH_6ZK__

I don't know if GCC uses __ARM_ARCH_6ZK__ for other ARM models, or if we should select a different value for CPU_MODEL_NAME.
Whatever you think is best.

Alan
